A roof that's gone a few years without attention often shows patches of moss or algae, particularly on north-facing slopes or under overhanging branches. It's more than a cosmetic issue, since trapped moisture can affect the tiles underneath over time.
Working at height on a sloped roof carries genuine risk, and an incorrectly used pressure washer can crack tiles or force water under slates. Most homeowners find it safer, and often cheaper overall, to bring in a roof cleaner with the right harnesses and softwashing kit.
A standard house roof usually takes a professional roof cleaner around a day, longer if there's heavy moss cover or scaffolding is required.
Roof cleaners covering Hawarden typically also work in Flint, Deeside, Mold and Buckley, so it's worth comparing a few quotes on Bark before booking.
Bark's data suggests roof cleaning in Hawarden typically costs £400 to £1,000 per job, roughly £8.50 to £14 per square metre. The total depends on your roof's size, access, and whether it's a manual scrape and biocide treatment or a full steam clean.
